I did exactly as you did and BOOM:) it works. Thank you 12voltvids for sharing this video. God bless you and your family.

@@ismailjasat4449 Totally! I work on these (buy / sale) and I too thought the HD was fried - Power adapter switch and it works!!!

5 years later DVR and cameras going strong.

I'm on power supply number 3 now and fan #2. The fan on the processor will eventually slow down and cause the processor to overheat and the unit starts rebooting. A new fan solves that issue.

I saved you guys the cursing, as I thought my hard drive had failed too, and went to the trouble of swapping it out only to get the same error. Then the light bulb went on and I swapped the power supply. Walla, booted up. So I put the original drive back in and fired up the camera and made the video. I didn't initially shoot the hard drive swap because where the DVR was located it isn't accessible with the camera. It is in a security cabinet, and I actually removed it, and just had it balanced on a little table to shoot. So it may seem that I just "knew" the adapter was bad. Not true, I had worked on this for quite some time before I clued in, because this unit was not that old, I didn't think the adapter would fail that fast. But this isn't the only trouble I have had with this. The fan on the CPU also failed first, and caused it to overheat and start rebooting, so I stuffed a new larger fan from a laptop in there.

What happens is filter capacitors on the secondary side dry up and the ESR goes up. Under no load the voltage will appear normal, but under load the voltage fluctuates and that causes the rebooting issue.

Bad power adapters cause many problems. Even the liner type but especially the switch mode type.

It took me awhile to find it too. I checked a bunch of stuff before stumbling onto the power supply. It's a very common failure of all electronics. We have them fail on pvrs at work all the time. Many techs just swap the Pvr and not the power supply because it is in behind a cabinet or something and they are too lazy to fish the power cord. Then the new one acts up and I get dispatched to an angry customer that tells me that the box has already been replaced. First thing i ask. Did the previous tech change the power brick. Usually the answer is "I don't know" because especially now with covid we don't want customers hanging around too close while we work on the house. I pull the power brick, find it is usually hot as a firecracker and covered in dust confirming that it wasn't changed last week. Swap the power supply and guess what, problem solved.

97000 systems fixed!

Mine still going strong.

Mine has been going now for over 10 years I'm on the third power supply for the unit and the second one for the cameras and I'm on the second fan for the CPU. I just used a cheap fan that I found in a computer shoe horned it into the case problem solved

2.5 amp 30 watts

Sure you could replace it with an SSD and you will be replacing it every year or sooner as SSD are not designed for constant write cycle. They have limited writes and after that the memory cells start to fail and data vanishes. You have no idea how many SD cards i have burned through using them with security cameras. One day they work and the next they are blank.

sumesh77 The reliability of any electronic devices depends on how cheap the manufacture was when sourcing power adapters. Had it come with a nice linear supply with a big iron transformer it would never fail. But copper costs more than a bunch of capacitors and transistors.

The one I am using is rated 2.5 amps and has been running for over 2 years, plus the adapter was not new, it was an old one from the recycle bin at work from an old cable box.

@@12voltvids Well, my Lorex 16 Ch unit uses a 3 amp. Any advice as to what causes a 0x01, 0x05 ?

Mine still humming along 24/7

Have you tried a new power brick.

I have had both the power supplies fail over time. It is the weak link.

The power supply is the weak link on this as is the cooling fan on the processor. When you hear it start to scream, it is time for a new fan. Otherwise the processor will overheat and the unit start rebooting.

You're welcome!

You need to use the correct voltage. The input voltage will be printed on the device

Okay so it is the input voltage I need to go by. Not the output? Thank you for the quick reply.

@@Melissa-ve2zw you need to select a power supply that is the same as the original. On the device you are powering will specify what is required. If the device requires 48 volts you need a 48v power supply. That is a odd voltage. That's what equipment designed for telecom runs at as the battery systems are all 48v. Most devices will operate on one of some pretty standard DC voltage. 12, 19, 24, 48. 19 is real common for laptops. The output voltage of the power needs to be the same as the input of the device unless the device is a multi voltage device which will clearly be labeled on the device.

@@12voltvids the input says 100-240V, 50/60 Hz and 1.5 A. The output says 48.0V , 2.0 A and 96.0W and this is for a Lorex 4K . Sorry so just to clarify I need all the volts for input and output to match exactly?

@@Melissa-ve2zw Yes this DVR operates on 48 volts.

Mine has failed twice (the power brick that is) and the camera power brick has failed too. This is the weak link on these units. Mine runs 24/7 and the only other thing that has failed is the fan on the processor on the DVR.

You just learned the most important part of troouobleshooting. If a device uses an external power supply brick or wall wart, swap that first before doing anything else because 90% of the time that is the fault. Now excuse me while I go over to a friends place and pull his head out of his ass. (and hand him a new wall wart for his DSL modem)

As long as it is 12 volts you can go higher in current. The DVR will only draw what it needs. If you undersize the power supply you will burn it out.

@@12voltvids thanks man, I appreciate the info.

Salwa Hussein Possibly or someone might be trying to hack your system. Do not ever take an "update " as that is how they get in and turn your DVR into bitcoin miner. Factory reset and choose a hard password. Will keep the hackers at bay. The power supply is likely causing your issue. My DVR recently had someone trying to break in. I just haven't done the video yet.

@@12voltvids Thank you for help. Did not change factory setting yet , as have not screen. Using Mobile and Internet to see outdoor camera only. Very poor usage! But I always suspect that at the same time every morning there is a beep like if someone is there. Any way now I cannot even open the camera. Will try to change the adapter. Appreciate your kind answer.

The power supply might be giving the correct voltage but not the correct current. So when the hard drive ties to start the power supply can not supply enough current and the voltage falls.

That's fine. I am using a 3 amp max on mine.

Genius! Thanks! I couldn't find a spare power cord and this solved my problem!
